Patent CA-2245171-C (CA)
Title: Smart telecommunications interface
Inventor: STELMAN BRUCE W
IPC: H04M1/215
Filed: 1997-03-27
Granted: 2001-05-15
Abstract: The present invention overcomes interface problems between proprietary handset ports on telephone base units and voice/data accessory products by allowing a user to automatically calibrate the telephone accessory product for an optimal interface match with the intended telephone base unit. This is accomplished through the use of a "Smart Interface Technology" (SIT) integrated chip set consisting of a full custom analog and semi-custom digital integrated circuit. The SIT incorporates three different methods for "learning" the characteristics of 4-wire port modular interfaces found in all telephone station sets. Basically, these methods determine the appropriate 4-wire terminal configurations, the transmit and receive channels of the intended telephone base unit, and adjust the channel sensitivities until an optimal and clear signal is provided for the user.

Abstract: An apparatus for restricting pivoting of a pivotal axle in a forklift. The forklift has an axle that is supported pivotally relative to a body frame. A damper is arranged between the body frame and the axle to permit and restrict pivoting of the axle. An electromagnetic valve locks the damper to restrict pivoting of the axle. The axle is free to pivot when the pivot angle of the axle relative to the body frame exceeds a predetermined reference angle. A controller refers to the pivot angle and other factors relating to vehicle stability when deciding whether to restrict pivoting of the axle.

Abstract: An electrochemical fuel cell comprises a pair of separator plates (222, 224) and a pair of fluid distribution layers (218, 219) interposed between the separator plates. At least one of the fluid distribution layers comprises a sealing region (240) and an electrically conductive, fluid permeable active region (230), and a preformed sheet material extending into each of the sealing region and the active region. An ion exchange membrane (214) is interposed between at least a portion of the fluid distribution layers, and a quantity of electrocatalyst (220, 221) is interposed between at least a portion of each of the fluid distribution layers and at least a portion of the membrane, thereby defining the active region. Compression of the preformed sheet material by urging of the pair of plates towards each other renders the at least one fluid distribution layer substantially fluid impermeable in a direction parallel to the major planar surfaces, in the sealing region. The performed sheet material included in the at least one fluid distribution layer thus has intrinsic sealing capability.      This approach reduces or eliminates the need for separate gaskets or sealing components and integrates several functions, such as sealing, fluid distribution, and current collection, in a single layer.

Abstract: The invention concerns a method for obtaining a vaccine against the pathogenic effects related to infection of a host by a retrovirus, in the event that the target cells of the retrovirus have a membrane receptor for a protein of the host and the viral infection induces an immune response directed both against an envelope protein of the virus and against a protein of the host. The method consists in preparing a vaccine agent based on a polypeptide comprising a fragment of an immunodominant and preserved zone of the retrovirus envelope protein, in a modified form such that the vaccine agent induces an immune response directed against the envelope protein and not against the host protein.

Abstract: For "Super Audio CD" (SACD) the DSD signals are losslessly coded, using framing, prediction and entropy coding. Besides the efficiently encoded signals, a large number of parameters, i.e. the side-information, has to be stored on the SACD too. The side information comprises the prediction filter coefficients and the probability table which have been used for encoding, an d which should be transmitted to the decoder. The smaller the storage capacity that is required for the side-information, the better the overall coding gai n is. Therefore coding techniques are applied to the side-information too so a s to compress the amount of data of the side information. The frames can be segmented, each segment having its own set of filter coefficients and probability table.
